A line mechanic describes his efforts to accomplish an engineering order and fleet campaign directive (fcd) to untie; reroute and use filler material for a right recirculation fan wiring bundle. A line inspector also notes the confusion involving the use of guideline tape in the fcd to secure the wire bundles.

Narrative:
I was assigned to accomplish the final inspection of an engineering order callout and fleet campaign directive revision-B; to inspect the right recirculation (recirc) fan wiring check; after aircraft maintenance technician (amt) X accomplished his task; which was to untie the wire bundle; reroute wire bundle and used filler strip provided. He tried to use the filler strip provided in the [part's] kit; but was not enough [filler] to secure the wire bundle on the clamp. He opted to use electrical guideline tape by which in the standard wiring practices manual (swpm) 20-10-12 is allowed. Also the swpm was pointed out on revision-B of the fcd. During my inspection; the guideline tape was not part of the fleet campaign directive and was rejected by maintenance control. It should [have] been filler material totally inside the clamp between the wire bundles. Air carrier revision that came later clearly stated that no tape allowed at all.
